Leptoglossus clypealis, the western leaf-footed bug, is a species of leaf-footed bug in the family Coreidae. It is found in Central America and North America. Adult L. clypealis are 18–19 millimetres (0.71–0.75 in) in length. They are brown with flared, leaf-like expansions near their feet and a pale band across their wings.
L. clypealis is commonly found on juniper, but can be a pest to agricultural crops. In the 1980s, Hasan Bolkan discovered that the leaf-footed bug was a cause of lesions on commercially produced pistachio crops. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Western Leaf-Footed Bug is recorded against all the insects logged in Denver (43 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
